TUMBLER FOR COMBINATION-LOCKS.

T0 'atZZ whom, t may concern.-

Beit known that I, WARREN H. TAYLOR, of Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements inTumblers for Combination-Locks; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the sanne.

My invention relates to tumblers for combination-locks, and is an improvement on the tumbler shown and described in Patent No. 233,950, granted to The Yale t Towne Manufacturing' Company as assignee of Emory Stockwell, November 2, 1880. In the Stockwell tumbler the two rings of the hand-change tumbler are yieldingly held together by a split wire ring located within a groove in the center of the outer and larger ring and engaging a peripheral groove in the smaller ring, the latter being of such dimensions that it can be inserted and removed from either side. The objection to this tumbler is that when it gets worn or when the center is carelessly placed in position it may rest sufficiently close to the neXt tumbler so that its movement will by contact drag the other around with it.

The object, therefore, of the present invention is to provide in a cheap and simple manner a two-part or hand-change tumbler with improved means for limiting the penetration of the inner ring, thus permitting of the introd ucton and removal of the inner ring from one side only and absolutely preventing the said inner ring from being pushed or working to a position where it or the larger ring carried tlliereby can bear upon the next adjacent tumb er.

With this end in view my invention consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in front elevation of a tumbler embodying my invention.. Fig. 2 is a view of its opposite face. Fig. 3 is aview of the two rings disconnected. Fig. 4 is a view in transverse section; and Fig. 5 is a View in front elevation, partly in section, showing the split ring, all the views being somewhat enlarged, so as to show up the details more prominently.

The class of tumblers to which this invention relates is of the lkind known as handchanging tumblers-that is, tumblers which when it is desired to change their combinations can be removed from the lock and the relative positions of the two parts composing' same changed.

Each tumbler consists of two rings of metal, one within the other, and for economy in the manufacture I take a single disk having a central opening and punch out the center thereof, thus forming one large ring 1 with a central opening 2 and a smaller ring 3. The outer ring l thus formed is provided with the usual gating or notch 4: and has stampedor engraved upon its front face the graduations 5 usually employed on tumblers of this variety. A series of notches and teeth 6, corresponding in number to the graduations 5 on its face, are formed in the interior edge of the circular opening in the ring 1, and a corresponding series of notches and teeth 7 are formed on the periphery of the inner and smaller ring 3, so that when the two rings are assembled all independent rotary movement of one on or in the other is absolutely prevented. To hold the two rings against lateral displacement, I provide the larger one with an lannular groove 8, in which is seated the split ring 9, which latter normally projects beyond -the edge of the teeth 6, but which can be expanded by the pressure thereagainst of the inner and smaller ring, the latter being also provided with a shallow peripheral groove l0, into which the split ring projects when the two rings are assembled.

In constructing the tumbler after the smaller ring 3 has been punched from the larger one the larger ring is placed on a hub and the metal on its rear side,.or theside opposite to that containing the graduations, caused to iiow by squeezing or rolling or other proper method against the hub, so as to produce a flange 11 around the rear face of the opening therein. The rear face of the inner and smaller ring is beveled, as at 12, so as to permit it to be readily introduced into the front side of the opening in the large ring l, and when pushed home the teeth of the smaller ring will mesh with the teeth of the larger ring, and these intermeshing teeth together with the split ring will prevent any accidental separation of the parts, while the overlapping ange 11 at the rear side of the opening in the larger disk will absolutely prevent any rearward creeping movement of smaller ring IOS Having fully described my invention, what I claim as new1 and desire to secure by Letters Patent, is-

A tumbler for a combination-lock composed of an outer ring having a flange or lip integral therewith and overlapping the central opening thereof at the rear, teeth formed on the inner periphery ot' the outer ring, an inner ring having the rear edge of its periphery beveled, teeth formed on the periphery7 of said inner ring and meshing with the teeth on the outer ring, and a split ring carried by the outer ring and engaging a shallow groove formed on the periphery of the inner ring.

In testimony whereotl I have signed this specification in the presence of two subscribing witnesses. l
